Each strand below contains 6 activities that were designed for a grade 5 class, but are adaptable for grades 4 or 6. Use the links on the strand pages to see teacher notes and ready-made task cards for each activity. If you see something you like scroll to the bottom of the strand page where you will find pdf versions of these files to print for use in your classroom. Pdf is especially useful for documents that are to be printed. To read pdf files you need Adobe Acrobat Reader on your computer. If you do not have Adobe Acrobat read about pdf. The source of every activity is stated in the teacher notes. For a list of all resources used for this kit, see the bibliography.
